This invention is in the field of wheat (Triticum aestivum L.) breeding,specifically relating to a wheat variety designated XW14B.

BACKGROUND OF INVENTION

There are numerous steps involving significant intervention in thedevelopment of any novel, desirable plant germplasm. The goal is tocombine in a single variety an improved combination of desirable traitsfrom the parental germplasm. These traits may include, but are notlimited to, higher seed yield, resistance to diseases and/or insects,tolerance to drought and/or heat, altered milling properties, abioticstress tolerance, improvements in compositional traits, and betteragronomic characteristics.

Wheat is grown worldwide and is the most widely adapted cereal. Thereare five main wheat market classes. They include the four common wheat(Triticum aestivum L.) classes: hard red winter, hard red spring, softred winter, and white (hard and soft). The fifth class is durum(Triticum turgidum L.). Common wheats are used in a variety of foodproducts such as bread, cookies, cakes, crackers, and noodles. Ingeneral the hard wheat classes are milled into flour used for breads andthe soft wheat classes are milled into flour used for pastries andcrackers. Wheat starch is also used in the paper industries, as laundrystarches, and in other products.

DETAILED DESCRIPTION

The present invention relates to a new and distinctive wheat (Triticumaestivum L.) variety designated XW14B, its seeds, plants, plant partsand hybrids. Variety XW14B represents a significant advancement in elitegermplasm.

Also provided are methods for making XW14B that comprise crossing wheatvariety XW14B with another wheat plant and processes for making a wheatplant containing in its genetic material one or more traits introgressedinto XW14B through backcross conversion and/or transformation or geneticmodification, and to the wheat seed, plant and plant parts producedthereby. Variants of wheat XW14B created by mutagenesis ortransformation, such as genetic modification, as well as a hybrid wheatseed, plant or plant part produced by crossing the variety XW14B or alocus conversion of XW14B with another wheat variety are also provided.

Wheat variety XW14B has shown uniformity and stability for all traits,as described in the variety description information provided herein. Ithas been self-pollinated a sufficient number of generations, withcareful attention to uniformity of plant type to ensure homozygosity andphenotypic stability. The line has been increased with continuedobservation for uniformity. No variant traits have been observed or areexpected in XW14B, as described, for example, in Table 5 at the end ofthis section.

Field crops are bred through techniques that take advantage of theplant's method of pollination, such as self-pollination, sib-pollinationor cross-pollination. As used herein, the term cross-pollinationincludes pollination with pollen from a flower on a different plant froma different family or line and does not include self-pollination orsib-pollination. Wheat plants (Triticum aestivum L.), are recognized tobe naturally self-pollinated plants which, while capable of undergoingcross-pollination, rarely do so in nature. Thus intervention for controlof pollination is needed for the establishment of superior varieties.

Provided are methods of producing progeny with a new combination ofgenetic traits by cross pollinating one wheat plant with another byemasculating flowers of a designated female plant and pollinating thefemale parent with pollen from the designated male parent. Suitablemethods of cross-pollination of wheat plants are described, for example,in U.S. Pat. No. 8,809,654, which is herein incorporated by reference,but other methods can be used, or modified, as is known to those skilledin the art.

A cross between two different homozygous lines produces a uniformpopulation of hybrid plants that may be heterozygous for many gene loci.A cross of two heterozygous plants each that differ at a number of geneloci will produce a population of plants that differ genetically andwill not be uniform. Regardless of parentage, plants that have beenself-pollinated and selected for type for many generations becomehomozygous at almost all gene loci and produce a uniform population oftrue breeding progeny. The term “homozygous plant” is hereby defined asa plant with homozygous genes at 95% or more of its loci.

Choice of breeding or selection methods depends on the mode of plantreproduction, the heritability of the trait(s) being improved, and thetype of variety used commercially (e.g., F1 hybrid variety, purelinevariety, etc.). For highly heritable traits, a choice of superiorindividual plants evaluated at a single location will be effective,whereas for traits with low heritability, selection can be based on meanvalues obtained from replicated evaluations of families of relatedplants. Popular selection methods which can be used include pedigreeselection, modified pedigree selection, mass selection, and recurrentselection.

The complexity of inheritance influences choice of the breeding method.For example, pedigree breeding, backcross breeding, single seed descent,and bulk breeding, which are each described in U.S. Pat. No. 8,809,654(incorporated herein by reference), can be used. Each wheat breedingprogram may include a periodic, objective evaluation of the efficiencyof the breeding procedure. Evaluation criteria vary depending on thegoal and objectives, but may include gain from selection per year basedon comparisons to an appropriate standard, overall value of the advancedbreeding lines, and number of successful varieties produced per unit ofinput (e.g., per year, per dollar expended, etc.).

Various recurrent selection techniques can be used to improvequantitatively inherited traits controlled by numerous genes. The use ofrecurrent selection in self-pollinating crops depends on the ease ofpollination and the number of hybrid offspring from each successfulcross. Recurrent selection can be used to improve populations of eitherself- or cross-pollinated crops. A genetically variable population ofheterozygous individuals is either identified or created byintercrossing several different parents. The best plants are selectedbased on individual superiority, outstanding progeny, or excellentcombining ability. The selected plants are intercrossed to produce a newpopulation in which further cycles of selection are continued. Plantsfrom the populations can be selected and selfed to create new varieties.

Wheat variety XW14B can be used as the female or the male parent inbiparental crosses in order to develop new and valuable wheat varietiesor hybrids. Wheat normally self-pollinates in nature. Cross pollinationof one wheat plant with another to produce progeny with a newcombination of genetic traits, can be carried out according to methodsknown to those skilled in the art. Wheat cross-pollination is achievedby emasculating flowers of a designated female plant and pollinating thefemale parent with pollen from the designated male parent. Methods ofcross-pollinating wheat plants for use in selection and advancement aredescribed, for example in U.S. Pat. No. 9,282,712, the disclosure ofwhich is incorporated herein by reference in its entirety.

Plant breeding methods may include analysis, comparison andcharacterization of the plant genome and the use of molecular markers,including techniques such as Starch Gel Electrophoresis, IsozymeElectrophoresis, Restriction Fragment Length Polymorphisms (RFLPs),Randomly Amplified Polymorphic DNAs (RAPDs), Arbitrarily PrimedPolymerase Chain Reaction (AP-PCR), DNA Amplification Fingerprinting(DAF), Sequence Characterized Amplified Regions (SCARs), AmplifiedFragment Length Polymorphisms (AFLPs), Simple Sequence Repeats (SSRs),Single Nucleotide Polymorphisms (SNPs) and Quantitative Trait Loci (QTL)mapping.

Molecular markers can also be used during the breeding process for theselection of qualitative traits. For example, markers closely linked toalleles or markers containing sequences within the actual alleles ofinterest can be used to select plants that contain the alleles ofinterest during a crossing or backcrossing breeding program. The markerscan also be used to select for the genome of the recurrent parent andagainst the markers of the donor parent. Using this procedure canminimize the amount of genome from the donor parent that remains in theselected plants. It can also be used to reduce the number of crossesback to the recurrent parent needed in a backcrossing program.

The production of double haploids can also be used for the developmentof homozygous lines in the breeding program and in the production of,for example, hybrid wheat using variety XW14B. Double haploids areproduced by the doubling of a set of chromosomes (1 N) from aheterozygous plant to produce a completely homozygous individual. Thiscan be advantageous because the process omits the generations of selfingneeded to obtain a homozygous plant from a heterozygous source. Hybridwheat can be produced, for example, in methods utilizing cytoplasmicmale sterility, nuclear genetic male sterility, chemicals, geneticmodification or a combination thereof.

Wheat variety XW14B can be crossed with one or more parental lines,followed by repeated selfing and selection, producing many new geneticcombinations. Selected germplasm can be grown under unique and differentgeographical, climatic and soil conditions with further selections beingmade during and at the end of the growing season.

Wheat varieties that are highly homogeneous, homozygous and reproducibleare useful as commercial varieties. There are many analytical methods,such as those described herein, which can be used to determine thehomozygotic stability, phenotypic stability, and identity of thesevarieties produced or derived from variety XW14B. Gel electrophoresis isparticularly useful in wheat. Wheat variety identification can occur,for example, through electrophoresis of gliadin, glutenin, albumin andglobulin, and total protein extracts.

Disclosed are plant breeding methods in which plant populations as wellas individual plants are evaluated for general health, agronomics, andstability at one or more stages. These evaluations can include, but arenot limited to, one or more of the following characteristics: plantarchitecture traits such as seedling coleoptile length, coleoptile color(presence of anthocyanin), juvenile plant growth habit, tillering, plantheight, straw strength or lodging, flag leaf carriage at boot stage,leaf width and length, glaucosity of stems, leaves and spikes,pubescence of leaves and spikes, spike shape, spike density, spikeawnedness, and plant color through-out stages of growth; plant growthcharacteristics, such as vernalization requirement, date for first stemjoint emergence, heading date, flowering date, physiological maturitydate and harvest maturity; tolerance to weather conditions, such as coldtolerance, resistance to heaving, tolerance to wet soils and standingwater, drought and heat tolerance; and grain characteristics, such asgrain yield, test weight, 1000 kernel weight, grain moisture, graincolor, grain shape, grain protein, flour milling yield and bakingcharacteristics.

During its development, wheat variety XW14B was assayed and/or plantedin field trials and evaluated for a variety of traits and/orcharacteristics as compared to check varieties. The property(s) ofappropriate check varieties include but are not limited to varietieswith a similar relative maturity, varieties known to be susceptible toone or more particular diseases, insect, pathogen, field condition,weather condition, soil type or condition, and/or crop managementpractice, varieties known to be tolerant or resistant to one or moreparticular diseases, insect, pathogen, field condition, weathercondition, soil type or condition, and/or crop management practice,varieties comprising one or more particular marker locus, and/orvarieties derived from another appropriate variety or having aparticular pedigree. Appropriate choice of check varieties forcomparison assures an appropriate baseline and valid qualitative orquantitative assessment of any test varieties.

In the development of XW14B, the plants can be tested for various traitsincluding, but not limited to grain yield, test weight, heading date,harvest maturity, plant height, straw strength, pre-harvest sprouttolerance, resistance levels to leaf rust, stripe rust, tan spot,Septoria tritici blotch, Stagnospora nodorum blotch, powdery mildew,Fusarium (scab), wheat yellow mosaic virus and soilborne mosaic virus,and grain characteristics such as flour yield, flour protein, and bakingcharacteristics.

Wheat variety XW14B, being substantially homozygous, can be reproducedby planting seeds of the line, growing the resulting wheat plants underself-pollinating or sib-pollinating conditions, and harvesting theresulting seed, using techniques familiar to the agricultural arts.

In one aspect, wheat plants, plant parts and seeds are provided whichhave all or essentially all of the characteristics set forth in Table 5.In one aspect wheat plants, plant parts and seeds are provided whichhave all or essentially all of the physiological and morphologicalcharacteristics of wheat variety XW14B, or all or essentially all of thephenotypic characteristics of wheat variety XW14B, representative seedhaving been deposited with the ATCC as disclosed herein.

Wheat variety XW14B can be further reproduced by tissue culture andregeneration. Tissue culture of various tissues of wheat andregeneration of plants therefrom is well known and widely published.Thus, in another aspect provided are cells which upon growth anddifferentiation produce wheat plants capable of having the physiologicaland morphological characteristics of wheat variety XW14B.

As used herein, the term “plant parts” includes, without limitation,plant protoplasts, plant cell tissue cultures from which wheat plantscan be regenerated, plant calli, plant clumps, plant cells, embryos,pollen, ovules, pericarp, seed, flowers, florets, heads, spikes, stems,stalks, leaves, roots, root tips, anthers, and the like. When indicatingthat a plant is crossed or selfed this indicates that any plant part ofthe plant can be used. For instance the plant part does not need to beattached to the plant during the crossing or selfing, only the pollenmight be used.

In one aspect, a wheat plant containing a locus conversion or anessentially derived variety of XW14B is provided. Essentially derivedvarieties may be obtained, for example, by the selection of a natural orinduced mutant, or of a somaclonal variant, the selection of a variantindividual from plants of the initial variety, backcrossing, ortransformation by genetic engineering, from the repeated use of varietyXW14B or being predominately derived from variety XW14B.

A locus conversion refers to plants within a variety that have beenmodified in a manner that retains the overall genetics of the varietyand further comprises one or more loci with a specific desired trait,such as male sterility, insect, disease or herbicide resistance.Examples of single locus conversions include mutant genes, transgenesand native traits finely mapped to a single locus. One or more locusconversion traits may be introduced into a single wheat variety.

Transgenes and transformation methods provide means to engineer thegenome of plants to contain and express heterologous genetic elements,including but not limited to foreign genetic elements, additional copiesof endogenous elements, and/or modified versions of native or endogenousgenetic elements, in order to alter at least one trait of a plant in aspecific manner. Any heterologous DNA sequence(s), whether from adifferent species or from the same species, which are inserted into thegenome using transformation, backcrossing, or other methods known to oneof skill in the art are referred to herein collectively as transgenes.The sequences are heterologous based on sequence source, location ofintegration, operably linked elements, or any combination thereof. Oneor more transgenes of interest can be introduced into wheat varietyXW14B.

In some examples, transgenic variants of wheat variety XW14B areproduced by introducing at least one transgene of interest into wheatvariety XW14B by transforming wheat variety XW14B with a polynucleotidecomprising the transgene of interest. In other examples, transgenicvariants of wheat variety XW14B are produced by introducing at least onetransgene by introgressing the transgene into wheat variety XW14B bycrossing.

In one example, a process for modifying wheat variety XW14B with theaddition of a desired trait, said process comprising transforming awheat plant of wheat variety XW14B with a transgene that confers adesired trait is provided. In other examples, the genome of wheatvariety XW14B is transformed by genetic modification using techniquesdescribed herein, such as the CRISPR/Cas system adapted for use inplants. Therefore, transgenic wheat variety XW14B cells, plants, plantparts, and seeds produced from this process are provided. In someexamples one or more desired traits may include traits such as herbicideresistance, insect resistance, disease resistance, decreased phytate,modified fatty acid profile, modified fatty acid content, carbohydratemetabolism, protein content, or oil content.

Numerous methods for plant transformation are known in the art,including biological, such as the use of Agrobacteria, and physical,such as biolistic and particle bombardment, plant transformationprotocols. In addition, expression vectors and in vitro culture methodsfor plant cell or tissue transformation and regeneration of plants suchas those known in the art can be used.

In general, methods to transform, modify, edit or alter plant endogenousgenomic DNA include altering the plant native DNA sequence or apre-existing transgenic sequence including regulatory elements, codingand non-coding sequences. These methods can be used, for example, totarget nucleic acids to pre-engineered target recognition sequences inthe genome. Such pre-engineered target sequences may be introduced bygenetic transformation such as genome editing or modification. As anexample, a genetically modified plant variety can be generated using“custom” or engineered endonucleases such as meganucleases produced tomodify plant genomes (see e.g., WO 2009/114321; Gao et al. (2010) PlantJournal 1:176-187). Another site-directed engineering method is throughthe use of zinc finger domain recognition coupled with the restrictionproperties of restriction enzyme. See e.g., Urnov, et al., (2010) NatRev Genet. 11 (9):636-46; Shukla, et al., (2009) Nature 459(7245):437-41. A transcription activator-like (TAL) effector-DNAmodifying enzyme (TALE or TALEN) is also used to engineer changes inplant genome. See e.g., US20110145940, Cermak et al., (2011) NucleicAcids Res. 39(12) and Boch et al., (2009), Science 326(5959): 1509-12.Site-specific modification of plant genomes can also be performed usingthe bacterial type II CRISPR (clustered regularly interspaced shortpalindromic repeats)/Cas (CRISPR-associated) system. See e.g., Belhaj etal., (2013), Plant Methods 9: 39; The Cas9/guide RNA-based system allowstargeted cleavage of genomic DNA guided by a customizable smallnoncoding RNA in plants (see e.g., WO 2015026883A1, incorporated hereinby reference).

Plant transformation methods may involve the construction of anexpression vector. Such a vector or recombinant construct comprises aDNA sequence that contains a coding sequence, such as a protein and/orRNA coding sequence under the control of or operatively linked to aregulatory element, for example a promoter. The vector or construct maycontain one or more coding sequences and one or more regulatoryelements.

A genetic trait which has been engineered into the genome of aparticular wheat plant may then be moved into the genome of anothervariety using traditional breeding techniques that are well known in theplant breeding arts. For example, a backcrossing approach is commonlyused to move a transgene from a transformed wheat variety into an elitewheat variety, and the resulting backcross conversion plant would thencontain the transgene(s).

Various genetic elements can be introduced into the plant genome usingtransformation. These elements include, but are not limited to genes;coding sequences; inducible, constitutive, and tissue specificpromoters; enhancing sequences; and signal and targeting sequences.

Provided are plants genetically engineered or transformed to expressvarious phenotypes of agronomic interest. Expression of genes can bealtered to enhance disease resistance, insect resistance, herbicideresistance, agronomic, grain quality, and other traits relative to acomparable wheat plant that does not contain the transformed element orto a comparable non-transformed plant. Transformation can also be usedto insert DNA sequences which control or help control male-sterility.DNA sequences native to wheat as well as non-native DNA sequences can betransformed into the wheat plants described herein and used to alterlevels of native or non-native proteins. Various promoters, targetingsequences, enhancing sequences, and other DNA sequences can be insertedinto the genome for the purpose of altering the expression of proteins.Reduction or increase in the activity of specific genes by genetictransformation or modification can effect gene silencing, genesuppression or gene over expression in the plants described herein.

Many techniques for gene silencing are well known to one of skill in theart, including but not limited to, knock-outs, such as by insertion of atransposable element, antisense technology, (see U.S. Pat. Nos.5,107,065; 5,453,566; and 5,759,829), co-suppression, RNA interference,virus-induced gene silencing, hairpin structures, ribozymes,oligonucleotide-mediated targeted modification (see, e.g., WO03/076574and WO99/25853), Zn-finger targeted molecules (see, e.g., WO01/52620;WO03/048345; and WO00/42219), use of exogenously applied RNA (see, e.g.,US20110296556), and other methods known to those of skill in the art orcombinations of the above methods.

A genetic trait, engineered into a wheat plant using transformationtechniques can be transferred into another line using traditionalbreeding techniques that are well known in the plant breeding arts. Thewheat plants described herein can be the donor or the recipient of thetransformed genetic trait. For example, a backcrossing approach can beused to move a transgene from a transformed wheat plant to an elitewheat variety to provide resulting progeny comprising a transgene. Asused herein, “crossing” can refer to a simple X by Y cross, or theprocess of backcrossing, depending on the context. The term “breedingcross” excludes the processes of selfing or sibbing.

Transgenic or genetically modified wheat plants described herein can beharvested to produce a foreign or modified protein in commercialquantities. The foreign or modified protein can be extracted from atissue of interest, such as a seed, or from total biomass by knownmethods. The approximate chromosomal location of the integrated ormodified DNA molecule can be determined from a genetic map generated,for example, via conventional RFLP, PCR, and SSR analysis.

Particular markers used for these purposes may include any type ofmarker and marker profile which provides a means of distinguishingvarieties. A genetic marker profile can be used, for example, toidentify plants of the same variety or related varieties or to determineor validate a pedigree. In addition to being used for identification ofwheat variety XW14B and its plant parts, the genetic marker profile isalso useful in developing a locus conversion of variety XW14B.

Methods of isolating nucleic acids from wheat plants and methods forperforming genetic marker profiles using SNP and SSR polymorphisms arewell known in the art. SNPs are genetic markers based on a polymorphismin a single nucleotide. A marker system based on SNPs can be highlyinformative in linkage analysis relative to other marker systems in thatmultiple alleles may be present. Methods for analyzing polynucleotidesfrom plants, plant parts or seeds described herein may includecontacting a polynucleotide from the plant, plant part or seed, such asfrom wheat variety XW14B with a molecular marker or with modifiednucleotides that facilitate sequencing of the polynucleotide. Thepolynucleotide may be isolated, separated or otherwise obtained from theplant, plant part or seed. Modified nucleotides such as dNTPs may beincorporated with the polynucleotides along with appropriate primers ina reaction mixture that facilitates sequencing. Sequencing can be doneusing any method known in the art.

A method comprising isolating nucleic acids, such as DNA, from a plant,a plant part, plant cell or a seed of the wheat varieties disclosedherein is provided. The method can include mechanical, electrical and/orchemical disruption of the plant, plant part, plant cell or seed,contacting the disrupted plant, plant part, plant cell or seed with abuffer or solvent, to produce a solution or suspension comprisingnucleic acids, optionally contacting the nucleic acids with aprecipiting agent to precipitate the nucleic acids, optionallyextracting the nucleic acids, and optionally separating the nucleicacids such as by centrifugation or by binding to beads or a column, withsubsequent elution, or a combination thereof. If DNA is being isolated,an RNase can be included in one or more of the method steps. The nucleicacids isolated can comprise all or substantially all of the genomic DNAsequence, all or substantially all of the chromosomal DNA sequence orall or substantially all of the coding sequences (cDNA) of the plant,plant part, or plant cell from which they were isolated. The nucleicacids isolated can comprise all, substantially all, or essentially allof the genetic complement of the plant. The nucleic acids isolated cancomprise a genetic complement of the wheat variety. The amount and typeof nucleic acids isolated may be sufficient to permit whole genomesequencing of the plant from which they were isolated or chromosomalmarker analysis of the plant from which they were isolated.

The methods can be used to produce nucleic acids from the plant, plantpart, seed or cell, which nucleic acids can be, for example, analyzed toproduce data. The data can be recorded. The nucleic acids from thedisrupted cell, the disrupted plant, plant part, plant cell or seed orthe nucleic acids following isolation or separation can be contactedwith primers and nucleotide bases, and/or a polymerase to facilitate PCRsequencing or marker analysis of the nucleic acids. In some examples,the nucleic acids produced can be sequenced or contacted with markers toproduce a genetic profile, a molecular profile, a marker profile, ahaplotype, or any combination thereof. In some examples, the geneticprofile or nucleotide sequence is recorded on a computer readablemedium. In other examples, the methods may further comprise using thenucleic acids produced from plants, plant parts, plant cells or seeds ina plant breeding program, for example in making crosses, selectionand/or advancement decisions in a breeding program. Crossing includesany type of plant breeding crossing method, including but not limited tocrosses to produce hybrids, outcrossing, selfing, backcrossing, locusconversion, introgression and the like.

Favorable genotypes and or marker profiles, optionally associated with atrait of interest, may be identified by one or more methodologies. Insome examples one or more markers are used, including but not limited toAFLPs, RFLPs, ASH, SSRs, SNPs, indels, padlock probes, molecularinversion probes, microarrays, sequencing, and the like. In somemethods, a target nucleic acid is amplified prior to hybridization witha probe. In other cases, the target nucleic acid is not amplified priorto hybridization, such as methods using molecular inversion probes (see,for example Hardenbol et al. (2003) Nat Biotech 21:673-678). In someexamples, the genotype related to a specific trait is monitored, whilein other examples, a genome-wide evaluation including but not limited toone or more of marker panels, library screens, association studies,microarrays, gene chips, expression studies, or sequencing such aswhole-genome resequencing and genotyping-by-sequencing (GBS) may beused. In some examples, no target-specific probe is needed, for exampleby using sequencing technologies, including but not limited tonext-generation sequencing methods (see, for example, Metzker (2010) NatRev Genet 11:31-46; and, Egan et al. (2012) Am J Bot 99:175-185) such assequencing by synthesis (e.g., Roche 454 pyrosequencing, Illumina GenomeAnalyzer, and Ion Torrent PGM or Proton systems), sequencing by ligation(e.g., SOLiD from Applied Biosystems, and Polnator system from AzcoBiotech), and single molecule sequencing (SMS or third-generationsequencing) which eliminate template amplification (e.g., Helicossystem, and PacBio RS system from Pacific BioSciences). Furthertechnologies include optical sequencing systems (e.g., Starlight fromLife Technologies), and nanopore sequencing (e.g., GridlON from OxfordNanopore Technologies). Each of these may be coupled with one or moreenrichment strategies for organellar or nuclear genomes in order toreduce the complexity of the genome under investigation via PCR,hybridization, restriction enzyme (see, e.g., Elshire et al. (2011) PLoSONE 6:e19379), and expression methods. In some examples, no referencegenome sequence is needed in order to complete the analysis. VarietyXW14B and its plant parts can be identified through a molecular markerprofile. Such plant parts may be either diploid or haploid.

In some embodiments, methods of treating XW14B with a mutagen and theplant produced by mutagenesis of XW14B are provided. Backcrossconversions of wheat variety XW14B are also described. A backcrossconversion occurs when modified or non-native DNA sequences areintroduced through traditional (non-transformation) breeding techniques,such as backcrossing. DNA sequences, whether naturally occurring,modified or transgenes, may be introduced using these traditionalbreeding techniques. Desired traits transferred through this processinclude, but are not limited to, nutritional enhancements, industrialenhancements, disease resistance, insect resistance, herbicideresistance, agronomic enhancements, grain quality enhancement, waxystarch, breeding enhancements, seed production enhancements, and malesterility. Descriptions of some of the cytoplasmic male sterility genes,nuclear male sterility genes, chemical hybridizing agents, malefertility restoration genes, and methods of using the aforementioned arediscussed in “Hybrid Wheat by K. A. Lucken (pp. 444-452 In Wheat andWheat Improvement, ed. Heyne, 1987). Examples of genes for other traitswhich can be used with the methods, plants and plant parts describedherein include: Leaf rust resistance genes (Lr series such as Lr1, Lr10,Lr21, Lr22, Lr22a, Lr32, Lr37, Lr41, Lr42, and Lr43), Fusarium headblight-resistance genes (QFhs.ndsu-3B and QFhs.ndsu-2A), Powdery Mildewresistance genes (Pm21), common bunt resistance genes (Bt-10), and wheatstreak mosaic virus resistance gene (Wsm1), Russian wheat aphidresistance genes (Dn series such as Dn1, Dn2, Dn4, Dn5), Black stem rustresistance genes (Sr38), Yellow rust resistance genes (Yr series such asYr1, YrSD, Yrsu, Yr17, Yr15, YrH52), aluminum tolerance genes (Alt(BH)),dwarf genes (Rht), vernalization genes (Vrn), Hessian fly resistancegenes (H9, H10, H21, H29), grain color genes (R/r), glyphosateresistance genes (EPSPS), glufosinate genes (bar, pat) and water stresstolerance genes (Hva1, mtlD). The trait of interest is transferred fromthe donor parent to the recurrent parent, in this case, the wheat plantdisclosed herein. Single gene traits, whether naturally occurring,induced by mutation or genetically altered, may result from either thetransfer of a dominant allele or a recessive allele. Selection ofprogeny containing the trait of interest is done by direct selection fora trait associated with a dominant allele. Selection of progeny for atrait that is transferred via a recessive allele requires growing andselfing the first backcross to determine which plants carry therecessive alleles. Recessive traits may require additional progenytesting in successive backcross generations to determine the presence ofthe gene of interest.

Methods of developing a backcross conversion XW14B wheat plant areprovided including the step of repeated backcrossing to wheat varietyXW14B. The number of backcrosses made may be 2, 3, 4, 5, 6, 7, 8 orgreater, and fewer than 50, 40, 30, 25, 20, 15, 10, 9, or 8. Thespecific number of backcrosses used will depend upon the genetics of thedonor parent and whether molecular markers are utilized in thebackcrossing program. Provided are plants and plant populations that areproduced from backcrossing methods, transformation, locus conversion, orotherwise produced, and combinations thereof and that retain at least70%, 75%, 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%,91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, 99.5%, 99.6%, 99.7%, 99.8%,or 99.9% or 99.95%, 99.98%, 99.985%, 99.99% or 99.995% of the geneticprofile of wheat variety XW14B. The percentage of the genetics retainedin the backcross conversion may be measured by either pedigree analysisor through the use of genetic techniques such as molecular markers orelectrophoresis. Such methods and techniques are described in U.S. Pat.No. 8,809,654, the disclosure of which is herein incorporated byreference for this purpose. The backcross conversion or locus conversiondeveloped from this method may be similar to XW14B for the resultslisted in Table 5. Such similarity may be measured by a side by sidephenotypic comparison, with differences and similarities determined at a5% significance level, when appropriate in environmental conditions thataccount for the trait being transferred. For example, herbicide shouldnot be applied in the phenotypic comparison of herbicide resistantbackcross conversion of XW14B when compared back to XW14B.

Described are methods for using wheat variety XW14B in plant breedingand plants and plant populations produced by such methods. For example,wheat variety XW14B can be crossed with another variety of wheat to forma first generation population of F1 plants. This first generationpopulation of F1 plants will comprise an essentially complete set of thealleles of wheat variety XW14B. Also provided are methods and plantswhich use transgenic or backcross conversions of wheat variety XW14B toproduce first generation F1 plants.

A method of developing a XW14B-progeny wheat plant comprising crossingXW14B with a second wheat plant and performing a breeding method is alsodescribed. An exemplary method for producing a line derived from wheatvariety XW14B is as follows. Wheat variety XW14B is crossed with anothervariety of wheat, such as an elite variety. The F1 seed derived fromthis cross is grown to form a homogeneous population. The F1 seedcontains one set of the alleles from variety XW14B and one set of thealleles from the other wheat variety. The F1 genome is 50% variety XW14Band 50% of the other elite variety. The F1 seed is grown and allowed toself, thereby forming F2 seed. On average the F2 seed would have derived50% of its alleles from variety XW14B and 50% from the other wheatvariety, but various individual plants from the population can have amuch greater percentage of their alleles derived from XW14B. The F2 seedis grown and selection of plants made based on visual observation and/ormeasurement of traits. The XW14B-derived progeny that exhibit one ormore of the desired XW14B-derived traits are selected and each plant isharvested separately. This F3 seed from each plant is grown inindividual rows and allowed to self. Then selected rows or plants fromthe rows are harvested and threshed individually. The selections basedon visual observation and/or measurements for desirable traits of theplants, such as one or more of the desirable XW14B-derived traits aremade. The process of growing and selection is repeated any number oftimes until a homozygous XW14B-derived wheat plant is obtained. Thehomozygous XW14B-derived wheat plant contains desirable traits derivedfrom wheat variety XW14B, some of which may not have been expressed bythe other original wheat variety to which wheat variety XW14B wascrossed and some of which may have been expressed by both wheatvarieties but now would be at a level equal to or greater than the levelexpressed in wheat variety XW14B. The homozygous XW14B-derived wheatplants have, on average, 50% of their genes derived from wheat varietyXW14B, but various individual plants from the population would have amuch greater percentage of their alleles derived from XW14B. Thebreeding process, of crossing, selfing, and selection may be repeated toproduce another population of XW14B-derived wheat plants with, onaverage, 25% of their genes derived from wheat variety XW14B, and withvarious individual plants from the population having a much greaterpercentage of their alleles derived from XW14B. Homozygous XW14B-derivedwheat plants that have received XW14B-derived traits are also provided.

In some instances, selection may or may not occur at every selfinggeneration, selection may occur before or after the actualself-pollination process occurs, or individual selections may be made byharvesting individual spikes, plants, rows or plots at any point duringthe breeding process described herein. In addition, double haploidbreeding methods may be used at any step in the process. In one aspect,the population of plants produced at each and any generation of selfing,each such population consisting of plants containing approximately 50%of its genes from wheat variety XW14B, 25% of its genes from wheatvariety XW14B in the second cycle of crossing, selfing, and selection,12.5% of its genes from wheat variety XW14B in the third cycle ofcrossing, selfing, and selection, and so on.

Also disclosed are methods of obtaining a homozygous XW14B-derived wheatplant by crossing wheat variety XW14B with another variety of wheat andapplying double haploid methods to the F1 seed or F1 plant or to anygeneration of XW14B-derived wheat obtained by the selfing of this cross.

Still further, methods for producing XW14B-derived wheat plants areprovided by crossing wheat variety XW14B with a wheat plant and growingthe progeny seed, and repeating the crossing or selfing along with thegrowing steps with the XW14B-derived wheat plant from 1 to 2 times, 1 to3 times, 1 to 4 times, or 1 to 5 times. Thus, any and all methods usingwheat variety XW14B in breeding, including selfing, pedigree breeding,backcrossing, hybrid production and crosses to populations are provided.Unique starch profiles, molecular marker profiles and/or breedingrecords can be used to identify the progeny lines or populations derivedfrom these breeding methods.

Also disclosed are methods of harvesting the grain of variety wheatvariety XW14B and using the grain as seed for planting. Embodimentsinclude cleaning the seed, treating the seed, and/or conditioning theseed. Cleaning the seed includes removing foreign debris such as weedseed and removing chaff, plant matter, from the seed. Conditioning theseed can include controlling the temperature and rate of dry down andstoring seed in a controlled temperature environment. Seed treatment isthe application of a composition to the seed such as a coating orpowder. Seed material can be treated, typically surface treated, with acomposition comprising combinations of chemical or biologicalherbicides, herbicide safeners, pesticides, insecticides, fungicides,nutrients, germination inhibitors, germination promoters, cytokinins,nutrients, plant growth regulators, antimicrobials, and activators,bactericides, nematicides, avicides, or molluscicides. These compoundsare typically formulated together with further carriers, surfactants orapplication-promoting adjuvants customarily employed in the art offormulation. The coatings may be applied by impregnating propagationmaterial with a liquid formulation or by coating with a combined wet ordry formulation. Examples of the various types of compounds that may beused as seed treatments are provided in The Pesticide Manual: A WorldCompendium, C.D.S. Tomlin Ed., published by the British Crop ProductionCouncil. Some specific seed treatments that may be used on crop seedinclude, but are not limited to, abscisic acid, acibenzolar-S-methyl,avermectin, amitrol, azaconazole, azospirillum, azoxystrobin, bacillus,Bacillus subtilis, Bacillus simplex, Bacillus firmus, Bacillusamyloliquefaciens, Pasteuria genus (e.g. P. nishizawae), bradyrhizobium,captan, carboxin, chitosan, clothianidin, copper, cyazypyr,difenoconazole, etidiazole, fipronil, fludioxonil, fluquinconazole,flurazole, fluxofenim, GB126, Harpin protein, imazalil, imidacloprid,ipconazole, isofavenoids, lipo-chitooligosaccharide, mancozeb,manganese, maneb, mefenoxam, metalaxyl, metconazole, PCNB, penflufen,penicillium, penthiopyrad, permethrine, picoxystrobin, prothioconazole,pyraclostrobin, rynaxypyr, S-metolachlor, saponin, sedaxane, TCMTB,tebuconazole, thiabendaxole, thiamethoxam, thiocarb, thiram,tolclofos-methyl, triadimenol, trichoderma, trifloxystrobin,triticonazole and/or zinc.

Seed varieties and seeds with specific genetic resistance traits can betested to determine which seed treatment options and application rateswill complement such varieties and genetic resistance traits in order toenhance yield. For example, a variety with good yield potential butloose smut susceptibility will benefit from the use of a seed treatmentthat provides protection against loose smut. Likewise, a varietyencompassing a genetic resistance trait conferring insect resistancewill benefit from the second mode of action conferred by the seedtreatment. Further, the good root establishment and early emergence thatresults from the proper use of a seed treatment will result in moreefficient nitrogen use, a better ability to withstand drought and anoverall increase in yield potential of a variety or varieties containinga certain trait when combined with a seed treatment.

Examples Examples 1-12: Assays Performed to Develop XW14B

The following examples provide descriptions of several assays that canbe used to characterize and/or select a wheat variety during one or morestages of variety development. Other methods and assays are availableand can be used in combination with or instead of the examples providedherein. Tables 2-6 provide further information on wheat variety XW14Bproduced from at least one or more assays or methods described in thefollowing examples.

Example 1: Stripe Rust Screening

Stripe rust is a fungal leaf disease that is most common in themid-southern United States in the early spring. Significant levels ofthe disease can be found in some seasons anywhere in North America. Theinfection often mostly occurs on the flag leaf but it may attack theentire plant, including the head. Natural infection of plants in thefield may be rated visually using a 1-9 scale, where 1 indicatescomplete susceptibility and 9 indicates complete resistance. Some majorgenes for resistance may be detected using controlled seedling screeningexperiments inoculated with specific races of the pathogen. There arealso molecular markers for QTL linked to some specific resistance genes.

Example 2: Leaf Rust Screening

Leaf rust is a fungal leaf disease that is most common in the southernUnited States in the spring and early summer. Significant levels of thedisease can be found in most seasons anywhere in North America. Theinfection is most damaging when it occurs on the flag leaf but it mayattack the entire plant, including the head. Natural infection of plantsin the field may be rated visually using a 1-9 scale, where 1 indicatescomplete susceptibility and 9 indicates complete resistance. Some majorgenes for resistance may be detected using controlled seedling screeningexperiments inoculated with specific races of the pathogen. There arealso molecular markers for QTL linked to some specific resistance genes.

Example 3: Leaf Blight Screening

Fungal leaf blights, including Tan spot, Septoria tritici blotch, andStagnospora nodorum blotch, are common in much of the North Americanwheat growing regions. The infection is most damaging when it occurs onthe flag leaf but it may attack the entire plant, including the head.Natural infection of plants in the field may be rated visually using a1-9 scale, where 1 indicates complete susceptibility and 9 indicatescomplete resistance.

Example 4: Scab Screening

Fusarium head blight or scab is a fungal disease that is common in muchof the North American wheat growing regions. Infection occurs duringflowering and is most severe when conditions are wet, warm and remainhumid. The disease infects flowers on the spike and will spread toadjacent flowers, often infecting most of the developing kernels on thespike. Natural infection of plants in the field may be rated visuallyusing a 1-9 scale, where 1 indicates complete susceptibility and 9indicates complete resistance. Infection may be induced in controlledscreening experiments where spikes are inoculated with specific sporeconcentrations of the fungus by spraying the spikes at flowering orinjecting the inoculum directly into a flower on each spike. There arealso molecular markers for QTL linked to some specific resistance genes.

Example 5: Powdery Mildew Screening

Powdery mildew is a fungal leaf disease that is most common in thesouthern United States in the spring and early summer. Significantlevels of the disease can be found in many seasons anywhere in NorthAmerica. The infection is most damaging when it occurs on the flag leafbut it may attack the entire plant, including the head. Naturalinfection of plants in the field may be rated visually using a 1-9scale, where 1 indicates complete susceptibility and 9 indicatescomplete resistance. Some major genes for resistance may be detectedusing controlled seedling screening experiments inoculated with specificraces of the pathogen. There are also molecular markers for QTL linkedto some specific resistance genes.

Example 6: Soilborne Mosaic Virus Screening

Soilborne mosaic virus is transmitted by the vector, Polymyxa graminis,which tends to be most common in low-lying, wet soils; particularlythose frequently grown to wheat. Symptoms appear in the spring as lightgreen to yellow mottling along with stunting and resetting plant growthin the most susceptible varieties. Natural infection of plants in thefield may be rated visually using a 1-9 scale, where 1 indicatescomplete susceptibility and 9 indicates complete resistance. Higherlevels of natural infection can be induced for screening by plantingwheat annually in the same field to increase the vector level.

Example 7: Wheat Yellow (Spindle Streak) Mosaic Virus Screening

Wheat yellow virus is transmitted by the vector, Polymyxa graminis, andis most common during cool weather conditions in the spring. Symptomsappear as light green to yellow streaks and dashes parallel to the leafveins. Symptoms often fade prior to heading as weather conditions becomewarmer. Natural infection of plants in the field may be rated visuallyusing a 1-9 scale, where 1 indicates complete susceptibility and 9indicates complete resistance.

Example 8: Flour Yield Screening

The potential average flour yield of wheat can be determined on samplesof grain that has been cleaned to standard and tempered to uniformmoisture, using a test mill such as the Allis-Chalmers or Brabendermill. Samples are milled to established parameters, the flour siftedinto fractions, which are then weighed to calculate flour yield as apercentage of grain weight.

Flour yield “as is” is calculated as the bran weight (over 40 weight)subtracted from the grain weight, divided by grain weight and times 100to equal “as is” flour yield. Flour yield is calculated to a 15% grainmoisture basis as follows: flour moisture is regressed to predict thegrain moisture of the wheat when it went into the Quad Mill using theformula

Initial grain moisture=1.3429×(flour moisture)−4.

The flour yields are corrected back to 15% grain moisture afterestimating the initial grain moisture using the formula

Flour Yield_((15%))=Flour Yield_((as is))−1.61%×(15%−Actual flourmoisture)

Example 9: Flour Protein Screening

The protein content as a percentage of total flour may be estimated bythe Kjeldahl method or properly calibrated near-infrared reflectanceinstruments to determine the total nitrogen content of the flour.

Flour protein differences among cultivars can be a reliable indicator ofgenetic variation provided the varieties are grown together, but canvary from year to year at any given location. Flour protein from asingle, non-composite sample may not be representative. Based on theSoft Wheat Quality Laboratory grow-outs, protein can vary as much 1.5%for a cultivar grown at various locations in the same/2 acre field.

Example 10: Sucrose Solvent Retention Capacity (SRC)

The solvent retention capacity (SRC) of wheat flour measures the abilityof the flour to retain various solvents after centrifugation. SucroseSRC predicts the starch damage and pentosan components, and can becorrelated to sugar-snap cookie diameter quality metrics.

Sucrose SRC is a measure of arabinoxylans (also known as pentosans)content, which can strongly affect water absorption in baked products.Water soluble arabinoxylans are thought to be the fraction that mostgreatly increases sucrose SRC. Sucrose SRC a predictor of cookiequality, with sugar snap cookie diameters decreasing by 0.07 cm for eachpercentage point increase in sucrose SRC. The negative correlationbetween wire-cut cookie and sucrose SRC values is r=−0.66 (p<0.0001).Sucrose SRC typically increases in wheat samples with lower flour yield(r=−0.31) and lower softness equivalent (r=−0.23). The cross hydrationof gliadins by sucrose also causes sucrose SRC values to be correlatedto flour protein (r=0.52) and lactic acid SRC (r=0.62). Soft wheatflours for cookies typically have a target of 95% or less when used bythe US baking industry for biscuits and crackers. Sucrose SRC valuesincrease by 1% for every 5% increase in lactic acid SRC. The 95% targetvalue can be exceeded in flour samples where a higher lactic acid SRC isrequired for product manufacture since the higher sucrose SRC is due togluten hydration and not to swelling of the water soluble arabinoxylans.

Example 11: Lactic Acid SRC

Lactic Acid SRC=Lactic Acid Solvent Retention Capacity. Lactic acid SRCmeasures gluten strength. Typical values are below 85% for “weak” softvarieties and above 105% or 110% for “strong” gluten soft varieties. Seethe above discussion of protein quality in this section for additionaldetails of the lactic acid SRC. Lactic acid SRC results correlate to theSDS-sedimentation test. The lactic acid SRC is also correlated to flourprotein concentration, but the effect is dependent on genotypes andgrowing conditions. The SWQL typically reports a protein-correctedlactic acid SRC value to remove some of the inherent protein fluctuationnot due to cultivar genetics. Lactic acid is corrected to 9% proteinusing the assumption of a 7% increase in lactic acid SRC for every 1%increase in flour protein. On average across 2007 and 2008, the changein lactic acid SRC value was closer to 2% for every 1% protein.

Example 12: Molecular Screening

As shown in Table 5, plants were analyzed at various times throughoutthe development of XW14B for specific alleles for scab resistance. Asdiscussed above, and as is known to those skilled in the art, othertraits can also be screened by molecular analysis.

Example 15: Breeding History, Properties and Adaptation of Wheat VarietyXW14B

Wheat variety XW14B is a common, soft red winter wheat (Triticumaestivum L.) Variety XW14B demonstrates excellent yield potential,excellent stripe rust and powdery mildew resistance, very goodresistance to soil borne mosaic virus, and good resistance to Fusariumhead blight (scab) and leaf rust. Variety XW14B has medium-earlymaturity relative to other varieties in the primary region ofadaptation. It has shown adaptation to the northern soft wheat regionsbased on tests conducted in Arkansas, Delaware, Georgia, Illinois,Indiana, Kentucky, Michigan, Missouri, Mississippi, North Carolina,Ohio, Pennsylvania, Tennessee, Virginia and Ontario, Canada.

Wheat variety XW14B was developed by from a cross between threehomozygous lines W980281V1, 25R62 and W000450F1 B. Wheat variety XW14B,being substantially homozygous, can be reproduced by planting seeds ofthe line, growing the resulting wheat plants under self-pollinating orsib-pollinating conditions, and harvesting the resulting seed, usingtechniques familiar to the agricultural arts. The breeding history ofXW14B is described below in Table 6.
